The experimental device adopts a double-sided structure, that is, an experimental platform provides a place for two groups of four students to conduct pneumatic and hydraulic tests. It can conduct double-sided comprehensive pneumatic and hydraulic experiments at the same time, optimize and share resources, and improve product performance. Its overall structure is simple and practical.

With this training equipment, you can carry out pneumatic control and hydraulic control circuits and corresponding basic application experiments. It can also be integrated with each other to carry out the following experiments: realize gas-electric control, gas-hydraulic control, electro-hydraulic control and gas-electro-hydraulic integrated control.

Under socialist conditions, strengthening vocational training is conducive to accelerating the training of technical and professional backbone and skilled workers to meet the needs of national economic development for specialized personnel; It is conducive to improving the cultural quality and technical level of workers and promoting the improvement of labor productivity and economic benefits.

By measuring the air temperature and humidity at different points, air cooling, heating, humidification and dehumidification can be analyzed. In addition, some indoor and outdoor temperature and indoor humidity simulators are also included to verify the logic of the control system under all conditions that may occur in the air handling unit. Provide software for monitoring voltage, current, frequency, power, power factor, pressure, flow, etc., which can be displayed on PC in real time and can print reports. II The training plan uses the humidity chart to study the changes that the air experiences in different parts of the air handling unit, namely: sensible heat, steam humidification, cooling and dehumidification. Evaluate the heat balance corresponding to different parts of the air handling unit, analyze the operation of AHU temperature and humidity controller, direct and reverse action proportional control, open/close step control, damper temperature control, attached: English general refrigeration manual, English theoretical experiment manual.
